  • Required/Applied Condition:  AR-727CM, AR-401RO16, AR-721H or any controller reader , AR-321L485
  • Function: When 721H and 401RO16 connect to the same HUB by different 727CM, 721H can control 401RO16 output.
  • Problem Description:

          AR-401RO to be connected via ethernet to the hub.

          Also to the same hub customer would like to connect 2 x AR721HV with one AR-727CM.

          If a card is flashed from whichever AR721HV we would like to operate certain outputs of  AR-401RO, depending on user privilege.

  • Problem Solving

          Step.1 Hardware configuration:

          2 units of AR-727CM

          Setting the first unit with IP: 192.168.1.172, setting the second unit with IP :192.168.1.171

          2 units of 721HV3 with node ID 001 and node ID 002

          1 unit of AR-401RO16

          1 unit of AR-321L485


Notes: TTL communication signal is less than 2 meter, so if the distance between two 721H or many 721H is longer than 2 meter, you should connect each721H with each 727CM separately.

Step.2 Setting IP parameter:

  1. Set Channel 1 parameter of the second 727CM with IP: 192.168.1.171 as server according to the following figure:

Channel 1 setting:

Protocol: UDP

Operation Mode: Server

Local Port: 1621

Remote Port: 0

Remote IP: 0.0.0.0

Baud Rate: 4800

Date Bits: 8

2. Set Channel 1 parameter of the first 727CM with IP: 192.168.1.172 as client according to the following figure:

Channel 1 setting:

Protocol: UDP

Operation Mode: Client

Local Port: 1621

Remote Port: 1621

Remote IP: 192.168.1.171

Baud Rate: 4800

Date Bits: 8

Set Channel2 parameter of the first 727CM with IP: 192.168.1.172 as server according to the following figure:

Channel 2 setting:

Protocol: TCP

Operation Mode: Server

Local Port: 1623

Remote Port: 0

Remote IP: 0.0.0.0

Baud Rate: 9600

Date Bits: 8

Step.3 When the two 721H connect to PC by the Channel 2 of 727CM with IP: 192.168.1.172

Pls pay attention to select the right node number, IP address , Port :1623 in 701server according to the following figure:
